In our previous Scala tutorial<\/strong><\/a>, we had discussed Scala Case Class<\/a><\/strong>, now we are going to study Scala Method Overloading. In addition, we will learn example of Overloading Methods in Scala.
\nLet\u2019s begin Scala Method Overloading.<\/p>\n

What is Scala Method Overloading?<\/h3>\n

Scala Method overloading is when one class has more than one method with the same name but different signature. This means that they may differ in the number of parameters, data types<\/a><\/strong>, or both. This makes for optimized code.
\nLet’s discuss Scala String Method with Syntax and Method<\/a><\/strong><\/p>\n

Example of Overloading Method in Scala<\/h3>\n

Here, we are going to understand Scala Method Overloading with examples.<\/p>\n

Example – 1\u00a0<\/strong><\/h3>\n

Let\u2019s take an example with a different number of parameters.<\/p>\n

scala> class sayHello{\r\n     | def hello(){\r\n     | println(\"Hello, user\")\r\n     | }\r\n     | def hello(admin:String){\r\n     | println(\"Hello, \"+admin)\r\n     | }\r\n     | def hello(admin:String,guest:String){\r\n     | println(\"Hello, \"+admin+\", Hello \"+guest)\r\n     | }\r\n     | }\r\ndefined class sayHello\r\nscala> var h=new sayHello()\r\nh: sayHello = sayHello@406ad6d5<\/pre>\n
We defined a new object \u2018h\u2019 for this class. Now, what this prints depends on which version of the method it calls. This depends on how many parameters we pass it (which version of the method definition satisfies the call format).<\/p>\n
While one version addresses the admin, another address both- the admin and the guest. The default version just says hello to user.
\nRead about Scala Access Modifiers: Public, Private and Protected Members<\/a><\/strong><\/p>\n
scala> h.hello()<\/pre>\n
Hello, user<\/p>\n
scala> h.hello(\"Ayushi\")<\/pre>\n
Hello, Ayushi<\/p>\n
scala> h.hello(\"Ayushi\",\"Megha\")<\/pre>\n
Hello, Ayushi, Hello Megha<\/p>\n
Example – 2<\/strong><\/h3>\n
Now, let\u2019s try Scala overloading method with versions owning different types. This way, we can carry out the same functionality on different types depending on what the user asks for.<\/p>\n
scala> class Calculator{\r\n     | def sum(a:Int,b:Int){\r\n     | var sum=a+b\r\n     | println(sum)\r\n     | }\r\n     | def sum(a:Double,b:Double){\r\n     | var sum=a+b\r\n     | println(sum)\r\n     | }\r\n     | }\r\ndefined class Calculator\r\nscala> var c=new Calculator()\r\nc: Calculator = Calculator@1d3e5a05\r\nscala> c.sum(1,2)<\/pre>\n
3<\/p>\n
scala> c.sum(1.1,2.2)<\/pre>\n
3.3000000000000003
\nIn this example, we have two versions of the method \u2018sum\u2019- one that adds two integers, and the other that adds two floats. It then prints out the sum.
\nLet’s Learn Scala Environment Setup and Get Started with an IDE<\/a><\/strong>
\nSo, this was all about Scala\u00a0Method Overloading tutorial. Hope you like our explanation.<\/p>\n
Conclusion<\/h3>\n
Hence, we come to the end of Scala Method Overloading tutorial, we finally knew method\u00a0overloading in Scala with example. Do let us know what you think in the comments.
